Xiaonan Han, PhD
Assistant Professor
Department of Pediatrics; Division of Gastroenterology, Hepatology, & Nutrition 

Description of Research

Dr. Han’s research currently focuses on intestinal barrier dysfunction in inflammatory bowel disease (IBD). His laboratory has recently demonstrated that GM-CSF signaling in intestinal epithelial cells (IEC) is required for intestinal barrier function; furthermore, GM-CSF may maintain intestinal epithelial barrier function via epithelial STAT5 pathway. Dr. Han’s lab has created a series of cell-specific STAT5 knock out mice to study the role of STAT5 in the gastrointestinal tract. He is also interested in developing the herbal remedy for treatment of pediatric Crohn’s disease. 

Collaborations and Core Use

Dr. Han has used the Integrative Morphology, Gene and Protein Expression and Bioinformatics Cores in collaboration with Drs. Denson, Hogan, and Aronow to identify genomic signatures that predict response to treatment of Inflammatory Bowel Disease. Anticipated Core use: Integrative Morphology Core.
